I'm not sure which House you're doing, but since you were in the Redoran Canton, I'll assume it's that one. Here's a quick walk-through of the Redoran Stronghold.

1. Build the first phase of your stronghold.
1. Talk to Galsa Gindu at her home in Ald'ruhn's Manor District to start the process.
2. Travel to Ebonheart to receive the construction contract from Duke Vedam Dren.
3. Return to Galsa Gindu with the contract and the construction will begin.
4. After a few days, talk to Galsa again, who will ask you to check on the stronghold progress.
5. Talk to the foreman on Bal Isra, Bugdul gro-Kharbush, and return to Galsa with the news.
6. The first phase should be finished after a few more days.

2. Build the second phase of your stronghold.
1. Talk to Galsa Gindu at her home in Ald'ruhn's Manor District about the second phase.
2. Talk to Percius Mercius at the Fighters Guild in Ald'ruhn to recruit some guards.
3. Rescue Percius' friend, Frelene Acques, from the prison in the Hlaalu Canton in Vivec.
4. Report back to Percius who will send some men to guard your stronghold.
5. Return to Galsa to start the construction.
6. The second phase should be finished after a few days.

3. Build the third and last phase of your stronghold.
1. Talk to Galsa Gindu at her home in Ald'ruhn's Manor District about the third phase.
2. Speak with Hetman Guls from your stronghold's small village who will tell you that you need to attract some more single women.
3. Attract some women from Ald'ruhn, Tel Aruhn, Ald Velothi, or Suran.
4. Return to Galsa to start the construction.
5. The third phase should be finished after a few days.
